Why the woman's role is important in the movie 1987 (his girlfriend)

This part shows the woman's role in the movie 1987.
Actually, they say he is the criminal who caused the nation's number one major incident in Busan, and there is a reason why he is actually a decent person.
Perhaps the women he dated were prosecutors or elite journalists.
In fact, he actually studied better than that journalist.
But do you know what happens if those people say he is like this or like that?
It turns out like that. Just know that much. ^^
Those people know what his school days were like, so they say he is definitely not that kind of person.
